Abstract
Description
- 1. Field of the Invention
- This invention belongs to a field of an information provision apparatus for providing various information, and particularly relates to a method for inhibiting unauthorized use of information in the information provision apparatus for providing information using information stored in a detachable information storage medium.
- 2. Description of the Related Art
- In recent years, an information provision apparatus with a DVD (Digital Versatile Disk) which is a detachable mass information storage medium and a hard disk drive (HDD) which is likewise mass information storing portion has actively been developed. For example, in a vehicle-mounted navigation apparatus, a home-use video recorder, a personal computer, etc., various apparatus with such a configuration have been developed.
- In such an information provision apparatus, information previously stored in a commercially available DVD is protected by copyright in most cases, and a user who has bought the DVD duly (that is, has paid the information fees and copyright fees) is permitted to use the information stored in the DVD within the use restrictions.
- However, there was a problem that the DVD is delivered from a duly authorized user to another user and thereby another user who has not bought the DVD duly (that is, has not paid the information fees and copyright fees) copies information stored in the DVD into an HDD illegally and a situation of unauthorized use is caused.
- In such a background, various techniques are disclosed with respect to a method for inhibiting unauthorized use of information in the information provision apparatus for providing information using information stored in a detachable information storage medium.
- For example, a navigation apparatus constructed so that illegally copied data cannot be used is disclosed (see JP-A-2003-216504). That is, the navigation apparatus has a first data recording part for setting a first recording medium, a second data recording part for setting a second recording medium, data decision processing portion for deciding whether or not data is present in the first recording medium, and data selection processing portion for selecting one of data of the first and second recording media when the data is present in the first recording medium and stopping selection of the data when the data is absent in the first recording medium, so that the illegally copied data cannot be used since selection of the data is stopped when the data is absent in the first recording medium.
- Also, an illegal copy inhibition method constructed so that when a disk-shaped recording medium is loaded into an information processing apparatus, the type is identified and thereby when the disk-shaped recording medium loaded is a rewritable type, it is regarded as an error and processing is stopped to prevent an illegal copy is disclosed (see JP-A-6-302092). That is, the number of dent holes for identification is two in the case of a cartridge for rewritable type disk, so that a switch outputs two pulses. A counter counts the pulses outputted from the switch and outputs a count value 2. A disk type identification part decides that the loaded disk is a rewritable type disk from the output value of the counter. When a playback-only type disk cartridge is loaded, the switch only outputs one pulse and an output value of the counter becomes one, and the disk type identification part decides that the loaded disk is a playback-only type disk from the output value of the counter.
- JP-A-2003-216504 and JP-A-6-302092 are referred to as related art.
- However, in the conventional method as described in JP-A-2003-216504, there was a problem that a storage medium such as a DVD bought duly must always be attached to an apparatus and for a navigation apparatus etc., a DVD for map information cannot be replaced with a DVD for another information such as a movie.
- Also, in the conventional method as described in JP-A-6-302092, there was a problem that it is difficult to identify a type of a storage medium such as a DVD which is not loaded in a cartridge.
- The object of the invention is to provide an information provision apparatus capable of easily inhibiting unauthorized use of information stored in a detachable information storage medium.
- The invention provides an information provision apparatus having: a detachable information storage medium that stores information; an information storing portion that stores information read from the information storage medium; a processing portion that performs a reproduction processing of information stored in the information storing portion; an output portion that outputs information reproduced by the processing portion; and a clocking portion that counts an elapsed time since the information storage medium is detached from the information provision apparatus, wherein the processing portion stops the reproduction processing when the elapsed time exceeds a specified value.
- Therefore, it is possible to easily inhibit unauthorized use of information stored in a detachable information storage medium.

- (First Embodiment)
- An example of the case of being applied to a navigation apparatus mounted in a vehicle acting as a mobile unit will be described as a first embodiment of an information provision apparatus according to the invention.
-
FIG. 1 shows a diagram of the whole configuration of a navigation apparatus in the first embodiment of the invention. InFIG. 1 ,numeral 101 is a control unit acting as processing portion for controlling an operation of the whole apparatus, andnumeral 102 is DVD-ROM (Read Only Memory) acting as a detachable information storage medium in which road map information for updating is stored, andnumeral 103 is a DVD drive for reading information from the DVD-ROM 102, andnumeral 104 is a hard disk drive (HDD) acting as information storing portion for storing the road map information, andnumeral 105 is a display acting as output portion for displaying information, and numeral 106 is a GPS receiver acting as clocking portion for acquiring information about the present exact time and date based on information received from a GPS (Global Positioning System) satellite equipped with an atomic clock. - Generally, the
control unit 101 executes a navigation operation using the road map information stored in theHDD 104, and can update the road map information inside theHDD 104 by copying the road map information for updating from the DVD-ROM 102 to theHDD 104. - FIGS. 2 to 4 are flowcharts showing operations of the navigation apparatus in the first embodiment. The flowchart of
FIG. 2 simultaneously operates completely independently of the flowchart ofFIG. 3 . The flowchart ofFIG. 4 is a flowchart showing a common operation in a step of DVD determination processing in the respective flowcharts ofFIGS. 2 and 3 . - First, the flowchart of
FIG. 2 will be described.FIG. 2 shows a flowchart showing a basic operation of the navigation apparatus in the first embodiment. By turning on a power source, the navigation apparatus starts an operation, and step S201 shown inFIG. 2 starts. This step S201 is a step of acquiring the present time and date information sequentially calculated by the GPS receiver 106. When the time and date information can be acquired, the flowchart proceeds to step S202. - In step S202, the previous insertion time and date of the DVD-
ROM 102 recorded in a predetermined position of theHDD 104 are compared with the present time and date acquired in step S201 and elapsed time t since the previous insertion time of the DVD-ROM 102 is calculated. When the calculation is completed, the flowchart proceeds to step S203. - In step S203, the elapsed time t calculated in step S202 is compared with operation advisability determination time T0 which is a specified value and when t<T0 is satisfied, the flowchart proceeds to step S204 and when t<T0 is not satisfied, the flowchart proceeds to step S207.
- In step S204, the elapsed time t is compared with user notification determination time T1. When t<T1 is satisfied, the flowchart proceeds to step S211 and the navigation apparatus performs the operation normally. When t<T1 is not satisfied, the flowchart proceeds to step S205.
- In step S205, a previous notification message that “an operable period expires soon” is displayed on the
display 105. Thereafter, in step S206, the previous notification message is erased after a lapse of a certain time since the message display or by a user manipulation, and the flowchart proceeds to step S211 and the navigation apparatus performs the operation normally. - Thus, the apparatus can be prevented from being disabled suddenly by notifying a user before a predetermined time of the time and date which is a time limit of use.
- In step S207, a warning message that “an operable period is overdue” is displayed on the
display 105, and a user is prompted to insert the DVD-ROM 102 in which road map information for updating is stored, and it waits until the DVD-ROM 102 is inserted. - When the DVD-
ROM 102 is inserted, the flowchart proceeds to step S208 and it is determined whether or not the inserted DVD-ROM 102 is the same DVD-ROM 102 as that of the case of copying the road map information into theHDD 104. In step S208, processing of the determination is performed based on the flowchart ofFIG. 4 described below. - When it is determined that it is the correct DVD-
ROM 102 as a result of the determination in step S208, the flowchart proceeds from step S209 to step S210 and after the warning message is erased, the flowchart proceeds to step S211 and the navigation apparatus performs the operation normally. When it is not determined that it is the correct DVD-ROM 102 in step S208, the flowchart returns from step S209 to step S207 and display of the warning message is continued. - By steps S207, S208 and S209, the navigation apparatus does not operate normally until the correct DVD-
ROM 102 is inserted when t<T0 is not satisfied and the operable period is overdue. That is, by thecontrol unit 101, an operation for playing back various information recorded on theHDD 104 is stopped and does not function as the navigation apparatus. - In the case of a user who has bought the DVD-
ROM 102 duly, the user can soon insert the DVD-ROM 102 to use the navigation apparatus, but a user with unauthorized use cannot use the navigation apparatus because the user does not have the DVD-ROM 102. - Thus, unauthorized use of the road map information can be inhibited without performing complicated user authentication processing by obliging a user to insert the authorized DVD-
ROM 102 periodically. - Next, a flowchart of
FIG. 3 will be described.FIG. 3 shows a flowchart showing a brief operation of insertion time and date information updating processing of the DVD-ROM 102 of the navigation apparatus in the first embodiment. By turning on a power source, the navigation apparatus starts an operation, and step S301 shown inFIG. 3 starts. In this step S301, theDVD drive 103 is monitored and it waits until the DVD-ROM 102 is inserted and when the DVD-ROM 102 is inserted, the flowchart proceeds to step S302. - In step S302, it is determined whether or not the contents of the DVD-
ROM 102 are those of the same DVD-ROM 102 as that of the case of copying road map information into theHDD 104. In step S302, processing of the determination is performed based on the flowchart ofFIG. 4 described below. - When it is determined that it is the correct DVD-
ROM 102 as a result of the determination in step S302, the flowchart proceeds from step S303 to step S304. When it is not determined that it is the correct DVD-ROM 102, the flowchart returns from step S303 to step S301 and it waits until the DVD-ROM 102 is inserted again. - In step S304, time and date information sequentially calculated by the GPS receiver 106 is acquired. When the time and date information can be acquired, the flowchart proceeds to step S305.
- In step S305, the previous insertion time and date of the DVD-
ROM 102 recorded in a predetermined position of theHDD 104 are updated to the time and date acquired in step S304. - In the above manner, the insertion time and date of the DVD-
ROM 102 can be updated. - Next, a flowchart of
